Evidence for the survival of outer planetary systems to the white dwarf phase comes from observations of planetary material 'polluting' the atmospheres of white dwarfs. These observations are unique in providing the composition of exo-planetary material. A small subsample of polluted white dwarfs are those that host circumstellar dust and ...
